Overview
This device can quickly, accurately, and real-timely detect and calculate indicators such as the International Roughness Index (IRI), Structural Depth (SMTD), Rut Depth (RD), Bump (PB), Wear Index (PW1), Riding Quality Index (RQI), Observation Score (RN), test speed, and driving distance of various levels of highway pavement. It can provide comprehensive and efficient data support for completion acceptance, preventive maintenance, and pavement management systems (CPMS).
Performance Characteristics
1. The data acquisition and analysis software has a full Chinese interface. During the test, it can real-timely acquire, display, and store data on indicators such as the International Roughness Index (IRI), Structural Depth (SMTD), Rut Depth (RD), Bump (PB), Wear Index (PWI), Riding Quality Index (RQI), Observation Score (RN), test speed, and driving distance.
2. Core components are all original imports.
3. The system adopts an integrated modular design, making subsequent maintenance and upgrades quick, convenient, and simple.
4. A portable laptop computer is used for data acquisition.
5. The detected data can be directly imported into the CPMS pavement management system.
6. The detection technical indicators conform to national pavement acceptance and maintenance standards: "Standard for Quality Inspection and Evaluation of Highway Engineering" (JTGF80/1-2017), "Standard for Highway Technical Condition Assessment" (JTG 5210-2018), "Highway Subgrade and Pavement Field Testing Procedures" (JTG3450-2019); conforming to the Ministry of Transport's "Automated Detection Procedures for Highway Pavement Technical Conditions" (JTG/T E61-2014), "Vehicle-mounted Laser Pavement Levelness Instrument" (JT/T676-2009), "Vehicle-mounted Laser Pavement Structural Depth Instrument" (JT/T840-2012), and "Vehicle-mounted Laser Pavement Rutting Instrument" (JT/T6772009) industry standards.System Composition
